Warning: This is FAR from perfect and not comparable to publicly available decimal-point temps (such as from PWS'es), and this is only meant for those who wish to have decimal-point data (e.g. records) for their monthly summaries or daily data, as daily highs/lows are 5-minute averages of 1-minute data for ASOS. Have I made myself CLEAR?!
To get the decimal point daily high/low temps for an ASOS/AWOS site, do the following:
1. Go to mesonet.agron.iastate.edu/request/asos/1min.phtml and select the site of your choice
2. Choose the date/date range of choice (if you'd like to calculate for record highs/lows, look at NOWData beforehand).
3. Once you've got that downloaded, find the highest or lowest 1-minute temperatures spanning 5 minutes, sum them and divide them by 5
4. (optional) If you'd like decimal-points of the odd number, you can round the output to the nearest °C, as decimal points would always be an even number per the calculation above
Example for August 3, 2022 @ KEWN (time in UTC); the warmest high of 2022:
96 + 96 + 97 + 97 + 96 = 96.4°F (= 96°F reported in NOWData, and 6/24 hr highs)
